Steps to reproduce:

what happens
Get +0 actions.
Crossroads says:
Reveal your hand. +1 Card per Victory card revealed. If this is the first time you played a Crossroads this turn, +3 Actions.
When you play an Estate (inheriting Crossroads), you're still playing an Estate, so it is not the first time you're playing a Crossroads and you don't get the +3 Actions.
